拔出

The functions of SiC whiskers are realized by whisker bridging, pulling-out, and crack deflection.

SiC晶须补强增韧机理是晶须桥接、拔出和裂纹偏转。

On one hand,the plastic deformation of PA6 is restricted and restrained by glass fiber which can decrease the impact toughness of SGF-PA6;On the other hand,the debonding of fiber/matrix interface and the pulling-out of fiber can consume partial energy,so the impact toughness of SGF-PA6 can be improved.

另一方面，冲击断裂过程中的纤维/基体界面破坏和纤维拔出可吸收一部分能量(在断口分析中很少看到纤维的断裂，所以未考虑纤维断裂的影响)，这有增加复合材料冲击韧性的影响。

And the strengthening mechanism can be described as follows: WC cemented carbides have interlaced short-clubbed grain, and in the bend strength test, the microcrack generates at WC/WC grain boundary, and may be blocked by interlaced fine-clubbed grains during extending, which induce the intergranular pulling-out. Due to the pulling-out mechanism, fracture-extend energy is greatly expended, thus bend strength is increased. The wear mechanism is groove wear and spalling of WC grains.

热机械合金化合成的WC-Co硬质合金比传统方法制备的同类WC合金具有更高的强度，其机理是：热机械合金化合成的WC合金具有交替排列的短棒状组织，在三点弯曲试验中，微裂纹萌生于WC/WC晶界位置，受到交错排列的短棒状晶粒的阻碍，裂纹扩展以短棒状晶粒的拔出方式进行，极大地消耗了裂纹扩展的能量，从而提高了弯曲强度；合成试样的摩擦磨损过程以犁沟磨损和WC颗粒的剥落为主要特征。

Fracture behavior study showed that, reinforced of SiC or Si〓N〓 nanoparticles, or SiC whiskers is due to cracks deflection, or twist, or diverse, or stop during propagating, and bridging and pulling-out of whiskers, and accompanied by fracture of a few SiC nanoparticles and whiskers.

断裂机理研究表明：裂纹扩展过程中遇到纳米SiC晶粒、纳米Si〓N〓晶粒和SiC晶须时，将发生偏转、扭曲、分叉、终止及晶须的桥接、拔出，并有少量SiC晶粒、Si〓N〓晶粒和SiC晶须断裂。

For sample 2, the fibres get together in mass because of the bad dispersion and present the phenomenon of pulling-out and debonding. The bonding is worse at the interface between the fibres and the matrix. The material shows tough fracture, with a low intensity: if σ(subscript ⊥)= 45.8 MPa,σ(subscript ∥)=19.4 MPa.

试样2由于纤维的分散性不好，大量聚集在一起，在压缩载荷的作用下，存在着纤维的拔出、脱粘现象，界面结合较差，材料呈现韧性断裂，强度较低σ=45.8MPa，σ=19.4MPa。

The grains of sintered body were enlarged and the phenomena of particle pulling-out decreased with increasing alumina content. ZrO〓/Al〓O〓 sintered composite body could reduce the alumina grain size dramatically.

当ZrO〓含量较多时，烧结体颗粒较小，晶粒拔出现象明显，随着Al〓O〓含量的增加，晶粒长大，颗粒主要是穿晶断裂。

Sample 1 had no phenomenon of pulling-out and debonding of fibres under vertical compression load and the interface bonding intensity is strong between the fibres and the matrix. The material shows brittle fracture: if σ(subscript ⊥)=60.7MPa. However, sample 1 has the phenomenon of fibres debonding because of the shearing stress between the fibres and the matrix under parallel compression load. The material shows tough fracture:σ(subscript ∥)=52.6 MPa.

试样l在垂直纤维层方向压缩载荷作用下，没有出现纤维的拔出、脱粘等现象，界面结合较强，材料呈现脆性断裂：σ=60.7MPa；而在平行纤维层的压缩载荷作用下，纤维与基体存在剪切作用，存在纤维的脱粘，试样呈现韧性断裂：σ=52.6MPa。

Results show that chemical reaction between additives Al2O3 and Y2O3 accelerated the liquid phase sintering and the formation of the YAG non-crystalline,which was beneficial to improving fracture toughness of Cf/SiC composites.Higher sintering temperature resulted in the strongly bonded fiber/matrix interface.Fiber push-off,crack deflection and grains bridging are main toughening mechanisms of silicon carbide cera...

结果表明：烧结过程中，烧结助剂Al2O3、Y2O3之间发生化学反应，促进液相烧结，形成晶界间的次晶相YAG(3 Y2O3.5Al2O3)，有利于提高复合材料的断裂韧性；在较高烧结温度下，碳纤维、烧结助剂与基体间发生反应，形成较强结合界面；纤维拔出、裂纹偏转和晶粒桥联是碳化硅陶瓷的主要增韧机制。

"Then it will soon be time," and Vorontsov drew out his watch and pressed a spring.

&那将很快的时间&和沃龙拔出了他的手表、压弹簧。

I'm leaving for Hong Kong for my vacation, so I want to draw out some money for the trip.

为我的假期我正在向香港出发，因此我想要为旅行拔出一些钱。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
